You can define a default item catalog category (ICC) structure for use by items created within the ICC. To use the default structure, you must define items as follows:

• Engineering box checked

• Revision effectivity enabled

When creating a structure for the item, use the same structure type and structure name as the ICC structure. The ICC structure components then automatically default to the item's new structure.

Child ICC structures can inherit components from parent ICC structures as long as a valid parent ICC structure version falls within the child ICC version's effective date range.

Prerequisites

• Enable the use of item catalog category versions by setting the profile option "Enable PIM for Telco Features" to Yes.

• Create an item catalog category draft version. See: Defining Item Catalog Categories.

   To create an item catalog category structure:

1. In the Item Catalog Categories page, search for and select an item catalog category (ICC).

   Additional Information: You can only associate a structure to a root (parent) item catalog category.

2. In the Basic Information page, click Draft.

3. In the Transaction Attributes page, click Structure.

4. In the Structure page, select a structure type and structure name.

   Optionally, enter a structure description.

   Note: You cannot select a structure type and structure name if the parent ICC has a structure. The child ICC inherits the parent's structure type and structure name along with the parent ICC structure components. However, you can add components to the inherited structure at the child ICC level.

5. Click Create Structure.

   The Structure page refreshes with the structure header information and the First Level Components region.

6. Click Update to add components to the structure.

   In the Update Structure page, you can update the structure header information and add components.

   Additional Information: Any inherited components display, along with the name of the category from which they were inherited. If a parent ICC has a defined structure header, then the structure header information (structure type, structure name) defaults the child ICC structure.

7. Click Search and Add Components.

   You can perform a simple search in the Search and Add Components: Simple Search page or click Advanced Search.

   Alternatively, you can click Add Another Row.

8. In the Search and Add Components: Search Results page, select the items that you want to add as components to the structure.

9. Click Apply.

   This returns you to the Update Structure: (structure name) page.

10. In the Update Structure: (structure name) page, change the quantity of each component if desired.

11. Click Apply.

To remove a component from the structure

12. Optionally, in the Update Structure page, select the component to remove, then click Remove.

    Note: You cannot remove components inherited from a parent ICC structure.

13. Click Apply.

To add attribute values to the structure components

14. In the Structure page, you can add attributes to any component. Click the Additional Attributes icon for a particular component.

15. In the View Additional Attributes: (component) page, select the attribute group that contains the attributes you want to define.

    Note: You cannot update attributes for inherited components.

16. Click Update.

    In the Update Additional Attributes: (component) page, enter the attribute values.

17. Click Apply.

    This returns you to the View Additional Attributes: (component) page.

    You can add attribute values to as many attributes and attribute groups as necessary. Once you define all of the component's attributes, click Return to Structure Page.

Once you have finished defining the item catalog category's structure and transaction attributes, release the ICC to create a new version. See: "To release an item catalog category draft version" in Defining Item Catalog Categories.

   To update an item catalog category structure:

To update an item catalog category structure, you must lock the Draft version of the ICC.

1. In the item catalog category's Basic Information page, click Lock.

   If only the Unlock button is visible, then the ICC is already locked.

2. Click Draft.

3. In the Transaction Attributes page, click Structure.

4. In the Structure page, click Update.

   Additional Information: You cannot update inherited components or the structure type and structure name if they are inherited. If you change a structure type or structure name at the root ICC level, a warning appears, saying that this change will cause the deletion of any associated structure components and attribute values. If you accept the change, you can add new components and attribute values.

To update the components within a structure

5. In the Update Structure: (ICC Name) page:

   • Add or remove components as described above in "To create an item catalog category structure".

   • Change the quantity of components as necessary.

   • Click Apply.

To validate the structure

When updating the components within a parent ICC's structure, it is possible to create duplicate components further down the hierarchy. You can use the Validate Structure button to warn you when this problem occurs. The following example explains how the duplicate components problem can occur.

In this example, you create the following initial ICC structures.

Parent (Root) ICC Structure

• Component 1

• Component 2

Child ICC Structure

• Component 1 (inherited from Parent ICC Structure)

• Component 2 (inherited from Parent ICC Structure)

• Component 3

Later, you decide that Component 3 must exist at the Parent ICC structure level. When you add Component 3 to the Parent ICC structure and release this draft ICC version, you receive a warning that, by adding Component 3, Component 3 becomes a duplicate component in the Child ICC structure.

The draft version of the Child ICC structure now contains a duplicate component. You cannot release a draft version in this state. You have three choices:

1. Release a new version of the Parent ICC with Component 3 removed from the ICC structure.

2. Remove the initial Component 3 added at the Child ICC structure level.

3. Change the effective version date of either the Parent ICC or Child ICC so Component 3 is no longer inherited in this version of the Child ICC.

Users can avoid duplicate components by using the Validate Structure button before releasing an updated draft ICC.

6. After updating the components within a structure, in the Structure page, click Validate Structure.

   The Structure Validation Results page opens. It displays any duplicate components in relevant versions of other item catalog categories within the hierarchy.

   You can release the parent ICC version even though it causes duplicate components in child ICC structures, however you cannot release any draft child ICC versions that contain duplicate components.

To update structure component attributes

7. In the Structure page, you can change the attributes of any component. Click the Additional Attributes icon for a particular component.

8. In the View Additional Attributes: (component) page, select the attribute group that contains the attributes you want to change.

9. Click Update.

   In the Update Additional Attributes: (component) page, enter the new attribute values.

10. Click Apply.

   To update the structure header:

You can change the structure type and structure name of an ICC structure, but doing so deletes all components and their attributes.

1. In the Update Structure: (ICC Name) page, select a different structure type or structure name.

   The following warning message appears:

   Changing the structure type and/or the structure name will delete all components and their attributes. Do you still want to continue?

   If you click Yes, then the Update Structure: (ICC Name) page appears again, with all components removed.

2. Select the new structure type and structure name you want to use for the updated ICC structure.

3. Add components and attributes as described previously in "To create an item catalog category structure:".
